How to Import a Subscription in Clash: How IP, DNS, and Your Browser Environment Affect It

This article explains how to import a subscription into Clash and why you still may not be able to access the internet after importing it. It focuses on the relationship between subscription links, IP, DNS, and the browser environment, and is suitable for users trying Clash, Clash Verge, or Clash for Windows clients for the first time.

1. What is a Clash subscription, and what should you prepare before importing it?

A Clash subscription is usually a link starting with http or https that contains multiple proxy nodes and rule configurations. Users do not need to manually copy each node. They only need to import the subscription address into the client and then update the configuration. This site also organizes testable free node resources, but the stability of free nodes may vary depending on time,线路, and the number of users, so it is recommended to test latency after importing.

Before importing, please confirm three things: first, the subscription link has no extra spaces; second, the client version supports Clash configuration; third, your local network can normally access the subscription address. If the subscription itself cannot be opened, Clash will not be able to update it either.

2. How to import a subscription into Clash: general steps

1. Open the Clash client and go to the Profiles / Configuration / Subscription page. The exact name may vary slightly between clients.
2. Click a button such as “New,” “Add,” or “Import from URL.”
3. Paste the subscription link there. For the name, you can enter something like “Free Nodes” or “Backup Subscription” for easier identification.
4. After saving, click “Update / Refresh” and wait for the client to fetch the configuration file.
5. Return to the proxy page and select a node or use an automatic selection policy group.
6. Enable System Proxy, and enable TUN mode as needed.
7. Open a browser and visit a test website to confirm whether your IP has changed.

If you are using Clash Verge or a Clash Meta-related client, the process is basically the same: first import the subscription, then update the configuration, and finally select a node and enable the proxy. Do not just import it without enabling the proxy, otherwise the browser will still use the local network.

3. What do IP, DNS, and the browser environment each affect?

IP determines the exit location seen by websites. Successfully importing a subscription does not mean your IP has already changed. Only after selecting a node and routing traffic through Clash will websites show the proxy exit IP when you visit them. If the test page still shows your local IP, it is usually because the system proxy is not enabled, the browser is bypassing the proxy, or the current application does not use the system proxy.

DNS affects domain name resolution. A common situation is that a node appears available, but some websites will not open or load very slowly. This may be because DNS has been polluted, resolved to an abnormal address, or the rules are not splitting traffic correctly. You can enable DNS in the client settings, or switch to enhanced mode/TUN mode for testing. Ordinary users do not need to modify complex parameters and should prioritize the client’s default recommended configuration.

The browser environment can also cause misjudgment. For example, the browser may have other proxy extensions installed, Secure DNS enabled, cached old resolution results, or some websites may judge the environment based on cookies, language, or time zone. When troubleshooting, it is recommended to use an incognito window, disable unnecessary proxy extensions, and then test the IP and access results again.

4. Troubleshooting subscription import failures and connection failures

• If it says the download failed: check whether the subscription link has expired and whether it can be opened in the browser. If necessary, switch networks and update again.
• If the import succeeds but there are no nodes: the subscription content format may be incompatible, so try a subscription address that supports Clash.
• If the node has latency but web pages will not open: try switching nodes, updating the subscription, enabling the system proxy, or checking the DNS settings.
• If only the browser works but software does not: the software may not use the system proxy, so you can try TUN mode.
• If disconnections happen frequently: congestion or failure is common with free nodes, so it is recommended to keep multiple subscriptions as backups.

In summary, the core of importing a subscription into Clash is not complicated: paste the subscription link, update the configuration, select a node, and enable the proxy. What really affects the experience is often whether the IP has switched successfully, whether DNS is resolving normally, and whether the browser is bypassing the proxy. By checking each item step by step as described above, you can usually identify most problems.
